PROBLEM TO BE SOLVED: To provide a spectrophotometer capable of measuring the absorbance of a very small amount of a sample without using a sample cell. SOLUTION: The spectrophotometer is provided with a light source 2 for emitting measuring light, a sample holding plate 6 for holding a sample 4 in a liquid droplet state, a detection part 8 for detecting the transmitted light from the sample 4, an imaging part 10 for taking the image of the sample 4 held to the sample holding plate 6, an operational processing part 12 for calculating the light path length of the measuring light from the image of the sample 4 obtained in the imaging part 10 and calculating absorbance on the basis of the light path length and the detection data acquired in the detection part 8 and a display part 14 for displaying the operational processing result acquired in the operational processing part 12.
